A delegate is like a function pointer, and event is like a function.
When an event is raised, it calls each delegate that is attached to it.
Events are generic in that they can accept delegates that point to any function, as long as the delegates ' signatures match the signature of the event .
Events are points of attachment for delegates to receive calls from an object.
The difficult we do right away...
...the impossible takes slightly longer.

I know a little in C++ world by reading some basic parts of C++ Primer book and doing simple stuff by C++. I'm about in the middle of the Microsoft Visual C++/CLI Step by Step and trying to reach a middle level in C++, the language I love. I like to write Windows apps including the traditional way and also Windows store. Do you have any advice or recommendation to me as an improvement, getting much better or so? Thanks guys

As Richard indicates, nothing beats actually writing some code and learning by doing.
There is one book I really like which isn't on the reference page:
"C++/CLI In Action" by Nishant Sivakumar.

Hi all,
I want to use MD5 to hash message. I see some implementation in the internet but my problem is that my message is not a string but a packet type. Someone can help please?
regards

Hashing works on bytes, whether they are characters or not is not important.

Well, type of data is not important.
Anyhow you have to send data to MD5 with array so there is no important thing happened when you send char array or byte array.
The difference between your message and string is that use byte array or use char array.
So, you can send byte array which implements your message contents to HD5 instead of char array. That's all.

What do you want?
|
|
|
|

Beside the fact that no question is asked, there is no CLI in the code; this is all standard C++. I believe this is posted to the wrong forum.
|
|
|
|
|
what is the code all about? Please ask question what do you want.
I love to answer c++ question :P

when I debug my app within a break ,"Internal error: pc 0x112 in read in psymtab, but not in symtab"jump out. what's up to my app?

Looks like you have the wrong forum for this question.
You may get a better response from qtforum.org or stackoverflow.com.

Have you got an answer on your question about crash?
I'm having a similar problem and don't know why...

int _tmain() {
LPCTSTR strName("HideDriver.sys");
utils::DriverWork::Start(strName);
return 0;
}
/*this code causes error LNK2019: unresolved external symbol "public: static void __cdecl utils::DriverWork::Start(char const *)" (?Start@DriverWork@utils@@SAXPBD@Z) referenced in function _main */
it builds fine by including DriverWork.cpp but does not build by only including DriverWork.h,,,,???

The .h files do not get actioned by the build system or compiler, only insofar as they are included into the source via the .cpp files. The compiler will only get executed to convert a .cpp file (and its inclusions) into object code.

This looks more like unmanaged C++ than managed. You need to include the .lib file of the dll the function resides in into the linker input of your application.
The good thing about pessimism is, that you are always either right or pleasently surprised.

thnx,,,,but i am not sure which lib needs to include
|

Well, did you add DriverWork.cpp to your solution?
Well, I was experienced problem like you. Cause of error is that I include header file using #include keyword but know added header and source file to my solutions. Whenever I've added it to my solutions, error disappeared.
